I live in an apartment for senior citizens and we had a few bedbug incidences. They called in an exterminator and they use heat to get rid of them. I was really scared and went and got plastic covers for my box spring and mattress.

I know this is a creepy subject, but bed bugs are becoming rampant. There is a very save chemical called diatamaceous earth you put under all the legs of every bed and couch in your house so they call in it and die.
